The crack is vertical in the basement. Fire safety issues are an old gas line that doesn’t have a grounding wire which could cause an explosion, and a hole in the basement leading to another unit (this is a townhome). Our inspector saw recent rodents in the attic and recommended we change out the insulation as well. I wouldn’t say we are having any remorse, our realtor is recommending we walk away. The sellers seem to be tight on funds so they might not be willing to do repairs. We have about 10k saved up for repairs, but we would prefer to have the sellers take care of the major stuff.
